Well, usually it’s a surprise only to people who aren’t paying close attention and whose perception is skewed by their own biases.
In the current situation, it’s informative to remember this little tidbit from a month and a half ago, during the troop buildup but prior to the invasion:
https://www.justsecurity.org/80149/retired-russian-generals-criticize-putin-over-ukraine-renew-call-for-his-resignation/
If you just read the headline, it would be easy to come away with the wrong impression, that the Russian military is skeptical of Putin’s imperialist adventuring and wants him to resign and be replaced by someone more reasonable. This kind of viewpoint is reinforced by the dopey types who like to repeat the mantra about “the arc of history bending toward justice” as an answer for everything, or insist that liberal democracy is the natural evolutionary end state of civilization, or other equally self-congratulatory nonsense.*
But if you read closely, you realize that the criticism from the retired generals is not that Putin shouldn’t be invading Ukraine. Rather, the criticism is that Putin’s crappy leadership has been focused on enriching his feudal-lord friends, which allowed the Russian government, and especially the military, to fall into neglectful disrepair, thereby damaging Russia’s prospects for empire-building going forward. Further, specific to Ukraine, the retired generals argue that Putin was pursuing his goals badly — the breakaway territories offered a way to nibble away at the border zone in bits and pieces, but Putin was failing to engage the West diplomatically and push for recognition of those territories’ status, because he was consumed with selling a false version of Western belligerence and expansion to the Russian people. There was a way to bring Ukraine under the Russian umbrella, said the generals, but Putin’s strategy was having, and would continue to have, the opposite effect.
The point is that if Putin is, in fact, removed because he is seen to have failed Mother Russia, he will not be replaced by democratic reformers, and it will not symbolize Russia entering a path out of its modern dark age. He will almost certainly be replaced by hawkish hardliners, possibly by the military itself (which is why declaring martial law is a risky gamble for Putin; it necessarily requires him to trust the officer corps to help run the country, and not exploit the increased power to turn on him). Putin’s sin, in their eyes, lies not in his goals, but in stupidly overplaying a limited strategic hand. If Putin is ousted, these are the guys who are most likely to take over.
There are dark days ahead for the common Russian people.
* If the arc of history does bend toward justice, it bends slowly and inconsistently across many generations. Those who need comfort right now, however, use the maxim to insist that progressivism will break through on all fronts in their lifetimes, which is delusional. And liberal democracy has certainly been proven to serve people well in the long run, but it’s also not a natural “end state” that civilization will simply gravitate to of its own accord; it requires constant effort and vigilance to attain and hold.
